I used M track for tor the railway plants in the non-visible layout parts. For all visible layout parts I only used K-track, especially a lot of flexible track. The smallest curve radius is 35 cm, the largest gradient is about 6%. I tried to use large curve radiuses for visible layout parts, to achieve a natural impression. Another shadow station is still planned, it will be placed below the existing layout and realized with C tracks. The connection to the shadow station will beralized via the anterior variable segment. For a better appereance, all K tracks were laid on Merkur styroplast track bed. Turnout actuators were installed under the baseboard, most of them were also fitted with rotable (Roco-) turnout laterns. All rails were painted in a rusty coulour. Someof the bridges are usual Kibri and Märklin bridges, other bridges made with Hekidur sheets or soldered of brass sheet metal or etched brass parts. I'm working with light signal from Herei and Busch, and semaphores form Weinert, Viessmann and Fleischmann. The catenary system (Sommerfeld) has only been installed on the visible parts of the layout.

Mainly, I used convential relay technique for the layout's electrical equipment, and fewer electronics. I didn't realize an automatic control, because of the computer control (which I'm planning for the future), it's not necessary. The layout has been realized with digital control from the beginnings. First, I had a Märklin Control Unit 6020, then a 6021, now an Uhlenbrock Intellibox. Turnouts and signals are completely digitally controlled. Digital control offers the possibility to control quite a lot of trains via the track, so the catenary system was realized only in visible layout parts and without any electric funtions. From the beginning I had decided for controlling track section for the answering signals. On the newer layout parts I decided to use the coding of the direction like it had been described in the Märklin-Magazin 6/87 - two reed contacts and an electrionic connected downstream - so a safe impulse is generated.

The electric equipment was as well detailed as the terrain or the buildings. Two examples: a signal is showing Hp1 (green) only if really a train is approaching. In opposite direction, all signals can passed, without having to switch them to green. Running a shuttle trains - with the control car at the top of the train - the shutle car is holding in front of the signal. The lights are still burning also when the signal is showing red. For the buildings I have planned to light the single (!!!) rooms. Various different light change circuits (after a suggestion in the Märklin Magazin 2/89) are controling a number of different buildings at the same time, so that all rooms are lighted accidentally. Beacuse of this expensive construction, some buildings have up to 17 (!) bulbs. Of course there are street lamps where they would also be in "real life", and turnout lamps are lighted as well. No wonder that my transformer's power is going down very quickly when all lights are switched on at the same time ;-)) !
